Abstract: FIELD: chemical technology and non-ferrous metallurgy; production of lithium-containing fluorides for electrolytic production of aluminum. 
     SUBSTANCE: proposed method includes selective sorption of lithium from natural salting liquor followed by desorption of it with water, thus obtaining  eluate, solution LiCl containing also CaCl 2  and MgCl 2  at ratios dictated by composition of salting liquor. Then eluate is  concentrated, treated with water and Li, Mg and Ca carbonates settle, after which they are subjected to treatment with hydrofluoric acid for obtaining mixture of LiF, MgF 2  and CaF 2 . Proposed method may be also realized by settling Mg and Ca carbonates from starting liquor by soda solution for obtaining mixture of MgCO 3  and CaCO 3  at low content of Li 2 CO 3  and lithium carbonate is added to this mixture in the amount of 30-50% of mass of total content of components; then mixture is stirred and treated with hydrofluoric acid for forming LiF, MgF 2  and CaF 2  fluorides at content of LiF from 30 to 50%. Used as fluorine-containing reagent is hydrofluoric acid, gaseous fluorine and/or gaseous hydrogen fluoride. Use of natural salting liquor makes it possible to obtain fluorides at minimum content of K, Si and Cl admixtures, not exceeding 0.2% of masses. 
     EFFECT: enhanced efficiency.

Abstract: FIELD: oil and gas industry. 
     SUBSTANCE: this group of inventions relates to mechanism and method of removing fluids from a gas well bottom hole interval. The mechanism contains a tapering or bottleneck section where the flow of gas produced from the well allows a low-pressure zone to be obtained with a pressure lower than the ambient formation gas pressure. The mechanism also has a channel to provide passage for the flow from the previous location in the well to the low pressure zone. This channel has its first end in the previous location and its second end in the tapering section or above or under the tapering section with the smallest diameter and is essentially a pipe with at least one hole to let formation gas enter in between the previous location and the low pressure zone. The pipe has a flexible section or expansion joint and a float connected to the first end of the channel. The method provides use of the mechanism as described above.

Abstract: FIELD: gas-processing industry; methods and devices of the gas-dynamic separation. 
     SUBSTANCE: the invention is pertaining to the method of the gas-dynamic separation, for example, to the low-temperature treatment of the multi-component hydrocarbon gases (natural and petroleum), and also for the gas dehydration by separation and condensation from it of the aquatic and (or) hydrocarbon components and may be used in the systems of collection, preparation and reprocessing of the multi-component hydrocarbon gases. The method provides for the swirled feeding of the initial stream of the high-pressure multi-component hydrocarbon gas into the nozzle, the isenthalpic expansion of the gas with cooling at its outflow at the transonic or supersonic speed, condensation of the components in the expanded and cooled rotating gas stream, separating of the condensate from the gas, collection of the condensate in the area with the reduced pressure which is formed by ejection from it of the gas phase, the increase of the compression of the purified gas stream by its stagnation in the diffuser and removal of the purified gas and the condensate. Into the initial gas additionally introduce the condensable hydrocarbon components in the liquid or vapor phases, in the expanded and cooled swirling stream form the near-axial field consisting predominantly of the gas phase, and the peripheral field consisting of the gas-liquid mixture of the condensed and non-condensed components. The latter is withdrawn into the area of the reduced pressure where separation of the gas-liquid mixture is made into the liquid and the gas. The gas is ejected with the purified gas of the near-axial field. At that, the gas-dynamic separation is conducted a single time or many times. The technical result of the invention is the increased efficiency of the separation. 
     EFFECT: the invention ensures the increased efficiency of the separation.
